System Requirements


Windows, Mac OS X, Linux

  • Open Blender, and click File > User Preferences > Addons > Install from File...'
  • Browse for the Zip archive you downloaded and select it.
  • Find LDR Importer in the list of Addons (search for "LDR" if needed), and tick the check mark to activate it.
  • If you want to have the script activated at all times, click the Save User Settings button.

Setting the LDraw Folder Path

  • Click File > Import > LDraw Model (.ldr/.dat)
  • In the bottom left corner of your screen, under the Import Options: header, there is a small field with the label LDraw Path.
  • Modify the field with the proper folder path to your LDraw Parts Library installation path.
  • On Windows, it is attempted to detect the installation path in the most common locations, so you may not need to set it at all.
  • There are a few import options available, such as using high quality bricks and performing basic model optimization or using the original mesh.
  • Select whatever options you desire, choose the model you want to import, and click the Import LDraw Model button.
  • Your model will quickly be imported into the current scene using the desired options.
  • Note about materials: Material colors are render engine dependent. That is, if you are currently using the Cycles engine, it will uses Cycles node materials, and vice verse for Blender Internal.

That's it! You have successfully installed LDR Importer and can now import your LDraw models!

Please Note

  • If a brick cannot be found in the parts library, the import will suddenly stop with no visible error message. This is planned to be fixed as soon as possible.
  • MPD and Bricksmith models are not supported. These features are planned to be added as soon as possible.

Workaround: To import an MPD model, download MPDCenter and extract the seperate models from the MPD. More details are available on the MPDCenter website. There is currently no known workaround for Bricksmith models.

We are sorry for any inconvenience these issues may have caused.
